"Without the bypass kit, the oil pressure is about 1 bar less in the main journal gallery than in the front cover. We mesure the oil pressure in the main oil gallery, the sensor is connected to the ECU, we did an calibration for it. if the Oil pressure drops below an value x at an specific rpm, than we flash the MIL, if it drops 0.5 bar below that Limit, we limit the RPM to prevent bearing failure."
